Believe it or not i had the same idea a few weeks ago but I thought the angle of the filters when they were turned over was too great and would cause them to hang down. Also, I didn't know how to seal them to the shroud. When you finish and have some pics i'm going to try it.
Thanks

You can actually rotate the filter housings in the main body quite a bit. Even thought the openings are "shaped", they are flexible, and have enough play to make adjustments.
I don't know if I'll get to work on the project further this week (on vacation next week), but will update when I can.

It would be great to have a kit that had filters, templates, an add on shroud and instructions for this for say $199.00. If there were real gains I bet it would sell !!!

I've made my templates (out of stiff paper), and will hit the sheet metal brake when time allows. I don't think I'll go to the trouble to make a perfect seal, but should be able to contain most of the air. Personally, I'm more concerned with losing precious air to the radiator, than "ramming" air into the intake. As most of us already know, "ram air" is usually very small compared to the benifits of "cold air". I already know my mod is good for making "cold air"

water, AND the filter get dirty faster when they can get fresh air. I know that sounds stupid, but everything must fit into their "recommend service interval"
From past experience, one weekend at the track can fill your filter full of debris if you travel aggressively behind competitors (isn't that the point?).

I did it last night then drove about 50 miles to check it out. First impression is no SOTP difference but i did stop and feel the intake and it was cold. Not cool, but COLD. Everything from the filters to the manifold was cold. This has got to improve performance but not enough that I could sense it. The filters are high enough that I'm not worried about water. In fact they are about the same height as stock just upside down. My only complaint is my workmanship. I am not skillfull enough to have done this well. The shroud is pretty butched up-not something I'm proud of but it was difficult to cut in place.

same here, good results, but ugly construction. Once I build my templets to rivet to the tops/sides, I'll likely pull the shroud off and clean up my cuts., even though you won't be able to see it

thanks for the idea! I just completed and can easily tell a difference. The car simply pulls much harder and breaks the tires loose like never before. Though I've not dyno'd, I can say I have picked up a few free ponies...

My Imagination?
The only thing I've done is this CAI and removed the screen. I didn't notice any improvement but I liked the idea. It's been just over a week and the car seems stronger but I chalked that up to my imagination. Today on my way to work I needed to change lanes and gave it a bit too much gas, the tires broke loose (TC/AH on) unintentionally. That has never happened before. It took me by surprise. Is it the colder weather, my imagination or is the car running better?

I did something very similar but used cone K&N's. If someone wants to host/post the pictures I will e-mail them to you. My entire set-up cost 110 bucks and looks awesome with a chrome pipe, clean cuts, and the stock air bridge was adapted to fit the peices. I have no desire to change what I have especially due to the looks of the system.
My main goals were to get away from having to use paper filters and to get some cool air in the engine compartment/filters. I cut the shroud in a way that the flaps hang down blocking water from hitting the filters. I never drove in rain but I'm sure its as good as any other that breaths from the bottom.

I just finished removing the shroud and flipping over the stock air filter holders. And there is definately a difference in the acceleration of the car! In my mind seat of pants is all that matters. Now this would not be good to drive in the rain but is an improvement in breathing. Much more air gets into the engine comp. and she runs 10-15% cooler too!
